The important distinction
Feeling uncomfortable does not tell you whether it is safe to manage alone. Alcohol and sedative withdrawal can be dangerous; seek a medical assessment rather than stopping abruptly if you may be dependent.
What can I do next?
If you are planning to stop and are unsure about risk, speak with a clinician or withdrawal service first. Severe confusion, seizures, trouble breathing or inability to wake someone require 911.
